According to the type 1 Bentley manual, the changeover to the j-style rim (with the safety humps occurred on Oct. 10, 1967, but these would have been 4-bolt wheels. Your 64 would have had 5-bolt wheels, so I don't know what to think. Is there a date stamp on these type 1 wheels? Are you sure we're talking about the same thing, with respect to the j-profile? I think it refers to the little hump inside, that the bead has to pop over when you mount the tire and first inflate it. You can also feel a small depression on the "outside" of the rim, even after the tire is mounted. Russ was right about using inner tubes with radials and early rims. I had forgotten about that. The microfilm is no help here, because the j-profile rims superceeded everything else. There IS some interesting info here, however. These are the wheels listed, in order. 1) a wheel, discontinued with no replacement, used up to VIN 268,999 [early 64] 2) 311 601 025B, a 5-bolt wheel, 4-1/2j x 15, 269 000-315 220 883 3) 111 601 025K, a 4 bolt wheel, 4-1/2j x 15, 316 000 001-on 4) 311 601 025K, a 4-bolt wheel, 4-1/2j x 15, 313 2034 478-313 2500 000 M-976 5) 113 601 025, a 4-bolt wheel, 4-1/2j x 15, 314 2000 001-on, M-976 It's clear that wheels #2 & 3, and the ones they superceeded, are the ones everyone is familiar with. Okay, what's so interesting? What was different about wheel #1 that keeps wheel #2 from superceeding it? Did early cars have a different offset? What was M-976? It's not listed in the type 3 M-codes on the same microfilm. Wheel #5 is the first mention I've ever seen about a 74 type 3.
